KSB's "Jumbo" Sets Sail | Building a Solid Ecological Barrier for the Upper Yangtze
Recently, amidst much anticipation, the core equipment of the fourth phase expansion project of the Chongqing Jiguanshi Wastewater Treatment Plant—the KSB SPN 1200 vertical volute wastewater pump—held a grand delivery ceremony at Shanghai KSB Pump Co., Ltd. This not only marks the successful delivery of another crucial piece of equipment from KSB, but also signifies that a major environmental protection project safeguarding the Yangtze River is about to be equipped with a powerful "domestic heart"!
The fourth phase expansion project of the Chongqing Jiguanshi Wastewater Treatment Plant carries the dual mission of addressing the central environmental protection inspection rectification and the ecological problems of the Yangtze River Economic Belt, making it a highly anticipated key project in Chongqing.
Upon completion, the total treatment capacity of the Jiguanshi Wastewater Treatment Plant will reach 1.2 million m³/d (cubic meters/day), making it the largest wastewater treatment plant in western China and one of the top five in the country. This surging purification power will greatly enhance the wastewater treatment capacity of Chongqing's central urban area, providing solid support for building a vital ecological barrier in the upper reaches of the Yangtze River.
A 12-Meter-High "Giant" Heart
Participating in such a significant project is an honor, but also a heavy responsibility: as the "heart" of the entire wastewater lifting system, the pump sets provided by KSB face unprecedented challenges.
⏺︎ Giant Size: The SPN 1200 pump sets shipped this time exceed 12 meters in height from the bottom of the inlet bend to the top of the motor, resembling a steel giant.
⏺︎ Enormous Energy Capacity: To achieve the project's massive leap in processing capacity from 800,000 tons to 1.2 million tons per day, KSB has revolutionized the inlet pump house. By converting six of the original seven main pump units to 12,000 m³/h SPN1200 pumps and adding three additional SPN series pumps with capacities of 8,750 m³/h, 5,370 m³/h, and 2,100 m³/h, KSB Shanghai's newly configured pump unit not only achieved a qualitative leap in total delivery capacity but also brought unprecedented operational flexibility and reliability.
⏺︎ Challenging the "Giant": The enormous size and energy of the units placed extremely stringent demands on vibration, flow patterns, and energy efficiency. Every step of transportation, installation, and commissioning was an ultimate test of technology and experience.
Facing these challenges, the KSB technical team showcased its core strengths:
⏺︎ Advanced Hydraulic Modeling: Leveraging KSB's technological DNA to ensure excellent design from the outset.
⏺︎ CFD Flow Simulation: Digital twin analysis of the entire pump house to predict and optimize water flow patterns.
⏺︎ CAE Vibration Analysis: "Diagnosing" each pump unit to ensure rock-solid stability under high-speed operation.
Furthermore, KSB provided over 100 key process equipment units for this project, including submersible sewage pumps, impellers, and agitators, ensuring smooth project operation with a comprehensive product portfolio.
Precise Contract Fulfillment, Living Up to Expectations
"High standards and strict requirements for project quality control, comprehensive coordination of construction progress across multiple stages"—this was the project's commitment and a test for all suppliers.
As a key equipment supplier for the project, KSB Shanghai deeply understood the weight of its responsibility. Facing the dual challenges of tight project deadlines and high technical requirements, the KSB team rose to the challenge, demonstrating outstanding professionalism and strong execution capabilities. All departments worked together seamlessly, with meticulous coordination at every stage from design and production to delivery, strictly controlling quality.
As expected, KSB ultimately delivered the first batch of 6 vertical volute sewage pumps and over 100 submersible agitator pumps in the first half of the year, strictly adhering to the project schedule requirements.
This precise fulfillment of contractual obligations effectively ensured the smooth progress of the entire project. On June 30th of this year, the project successfully achieved initial water supply operation. All installed KSB products operated stably and performed excellently, laying a solid foundation for the project's phased success.
Behind this success lies KSB's commitment to its customers, its dedication to social responsibility, and proof of the strength of "German technology, made in China."
With the successful delivery of the SPN 1200 pump, we will continue our efforts to fully complete the delivery of the subsequent retrofit pumps for this project.
Every shipment is a fulfillment of a promise; every departure is a journey towards the mission of protecting our green mountains and clear waters. KSB will continue to contribute to China's environmental protection cause with its superior technology, reliable products, and professional services, working together with all partners to build a green future.
